Book Description
Regular physical activity is recommended for the prevention of many chronic diseases and maintaining healthy body composition. Although the beneficial effects of regular exercise are well known and used to promote exercise videos, the claims made in many advertisements are often not validated. PURPOSE: To determine the effects of two different types of high intensity interval exercise protocols in respect to heart rate (HR) during exercise and recovery, pulmonary O2 uptake (VO2), CO2 output (VCO2), caloric expenditure (CE), and substrate utilization during recovery, and psychological impacts of exercise on feelings in trained individuals. METHODS: Healthy subjects (n=15,11 F, 4 M, 21.8 ± 0.83 yrs, ± SE) participated in this study. Subjects underwent two familiarization sessions prior to data collection where they completed either the Insanity® Plyometric Cardio Circuit (INS) or Turbo Fire® HIIT 30 (TF) exercises in a randomized order. The HR was measured at rest (30 min), during exercise and recovery (60 min) and expressed as % of age-predicted maximal HR (APMHR) and peak HR. Gas exchange was measured at rest and recovery. Responses of VO2, VCO2, RER were averaged at rest and five minute intervals during recovery. The caloric equivalent value for RER was used to find CE (kcal/min) at rest and corresponding five minute intervals during recovery. RESULTS: There was no difference (P>0.05) in peak HR (TF: 176.8 bpm, INS: 179.7 bpm). There was no difference (P>0.05) in % APMHR reached (TF: 89.4%, INS: 90.9%). There was no difference in the amount of time spent at 61-70% (TF: 510s, INS: 630s) and 71-80% APMHR (TF: 575s, INS: 517s), but there was more time spent at 81-90% APMHR (TF: 576.4s, INS: 995s). Six out of 15 subjects reached>91%APMHR in TF, and nine out of 15 subjects in INS. The HR was higher (P0.05) after INS (55min). The recovery HR was higher (P0.05) than resting HR after TF and INS (60min). Values of VO2 were higher (P

Book Description
The popularity of high-intensity interval training (HIIT), which consists primarily of repeated bursts of high-intensity exercise, continues to soar because its effectiveness and efficiency have been proven in use by both elite athletes and general fitness enthusiasts. Surprisingly, few resources have attempted to explain both the science behind the HIIT movement and its sport-specific application to athlete training. That’s why Science and Application of High-Intensity Interval Training is a must-have resource for sport coaches, strength and conditioning professionals, personal trainers, and exercise physiologists, as well as for researchers and sport scientists who study high-intensity interval training.

Book Description
Abstract: This study compared the acute cardiopulmonary and metabolic effects of four high-intensity interval training (HIIT) protocols using varying intensities during the work and recovery periods. Eleven participants (5 males, 6 females) performed four, 20-minute HIIT protocols at a 1:1 "work:recovery" ratio on a cycle ergometer in random order. The work:recovery relative intensities, based upon previously determined maximum work rates, were: 80%:0%, 80%:50%, 100%:0%, and 100%:50%. Oxygen uptake, heart rate, blood lactate, and rating of perceived exertion were measured. Data were analyzed using a two-way, repeated measures ANOVA (p ≤ 0.05). Oxygen uptake and heart rate were expressed as a percentage of the peak values established during a prior graded exercise test. There were clear differences in physiological response between protocols. The 80:50 and 100:0 may produce the best combination of effects. The 100:50 produced the greatest physiological response, however, it may not be practical for the general population.
